mysql sphinx存儲引擎安裝

由於業務需求，需要在現有mysql中安裝sphinx的存儲引擎，要保證現有mysql運行的情況下完成。mysql也的確支持存儲引擎的在線熱插拔，下面介紹安裝步驟：

1、查看現有mysql的運行版本
# mysqladmin -u user -p pwd version
...
Server version 5.1.47-log
Protocol version 10
Connection Localhost via UNIX socket
UNIX socket /data/mysql_db/mysql.sock
Uptime: 15 days 2 hours 17 min 40 sec

2、下載mysql和sphinx
mysql：wget ftp://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.1/mysql-5.1.47.tar.gz
sphinx：wget http://sphinxsearch.com/downloads/sphinx-0.9.9.tar.gz

注意：mysql源碼包的版本一定要與當前運行的mysql版本一致！

解壓
# tar -xzvf mysql-5.1.47.tar.gz
# tar -xzvf sphinx-0.9.9.tar.gz

3、將sphinx-0.9.9下的mysqlse目錄複製到mysql目錄中
#cp -r sphinx-0.9.9/mysqlse/ mysql-5.1.47/storage/sphinx

build
# cd mysql-5.1.47
# sh BUILD/autorun.sh
#./configure
# make

注意：這裏到make這步即可，不用install

4、將make好的文件複製到當前運行的mysql目錄中
# cp storage/sphinx/.libs/ha_sphinx.* /usr/local/mysql/lib/mysql/plugin
更改所有者
# chown mysql.mysql /usr/local/mysql/lib/mysql/plugin/*

注：我當前運行的mysql目錄在/usr/local/mysql

5、登陸mysql加載sphinx引擎模塊
#mysql -u root -p -h localhost
# mysql> INSTALL PLUGIN sphinx SONAME 'ha_sphinx.so';
檢查引擎模塊是否正常加載
mysql> show engines;
